New Release Specification
General Description
The aTS51 is a high-precision CMOS temperature
sensor that provides a cost-effective solution for
applications
temperature monitoring. The aTS51 is ideally suited for
applications requiring high drive current. The aTS51
output voltage ramp is extremely linear and has a
slope of 10mV/°C. With a supply voltage of 2.7V to
6V, the aTS51 is accurate to ±1°C over a temperature
range of −40°C to 125°C and has a typical room
temperature accuracy of ±0.5°C. Reducing the supply
voltage to 2.7V does not change the negative and
positive temperature extremes.
does not require external calibration. Calibration of
each device is performed at the factory.
